Due to the powerful feature, we can apply them in a myriad of equipment. For example, IoT system connects different devices together. The process of it is to build a communication between devices and the cloud. Therefore, IoT has an increasing demand of data storage. Although Industrial Micro SD or SD cards are still using for storage, the devices are more intelligent and complicate. An IoT device usually has gateway to connect things to the cloud, which acts as a bridge to transfer data. Ensuring a stable data accessing, this bulk Micro SD card must be against harsh environments. Such as extreme temperature, high rate for dust and water resistance and X-ray. Thus, standard flash card is hard to meet these requirements.
In addition, Industrial memory cards are also friendly for medical equipment. As these devices are storing patient settings and data for a quick, accurate setup, they need to operate in any condition. Sometimes you may use it in high humidity, sometimes you have to work in extreme hot place. By and large the status of bulk memory card must be no faults and good reaction.
What else will still use Industrial memory cards? There is transportation vehicle, action cameras, embedded applications, Automotive, Data server, Networking and so on. All in all, it is a stringent storage and helpful for high performance.
MRT has developed a splendid series of industrial cards passing thorough tests. The storage group incorporate Micro SD, SD, CF, and SSD. In general, the shape and weight are same as regular card.

Meanwhile, consumer market sells more about standard products. All in all, we need go for professional factory like MRT3C. As only manufacturer has detailed introduction as well as datasheet, users can get complete answers there.
Tips for identify industrial memory cards (What are the differences between Standard NAND Flash and Industrial NAND Flash)
1.Temperature range
Industrial grade cards can be used in wider temperature, it is from -45C to 85C. However, consumer grade cards are only available from 0 to 65C or -25 to 85C.
2.Lifespan
Standard memory cards are usually using MLC and TLC flash, the life circle is 10,000 times at most. One time is one full writing and erasing. Industrial memory cards use SLC flash often, the life circle can be 30,000 times or more.
3.Performance
Undoubtedly Industrial memory cards lead a better performance due to its precise structure and raw material.
Industrial memory cards stand for profession, high technology, and sophistication. No matter embedded systems, GPS, military machines, or surveillance cameras, all of them can work dramatically perfect with industrial cards.

The new mobile phones in 2022 supporting external storage were few, such as the Sony Xperia 1 IV and Huawei Mate Xs 2. These new models support to use bulk Micro SD card. I’m not sure when mobile phones started progressively losing the ability to support such expansion. Ordinary consumers can only purchase phones with higher capacity if they wish to increase their memory space. Is it true that we don’t require bulk Micro SD cards expansion? A questionnaire study on memory card expansion for mobile phones gets start recently.
In the first, users were asked how important SD memory card expansion is to them, and we can see that 45% of the respondents said it was “very good but not very significant”. And nearly 40% said: “I will not buy a mobile phone without SD memory card expansion.” About 15% of the respondents selected “I don’t need it”
In the second poll question, “How much storage is in use on your mobile phone right now?” , 128GB to 256GB accounts for up to 35.58% of the respondents, and 64GB to 128GB is the second-largest group. Those who have more than 256GB make up the third group, and the remainder is in smaller proportions.
Manufacturers of mobile phones are gradually discontinuing SD memory card expansion. On the one hand, each additional hardware on phone will raise its price and weight due to the cost. On the other hand, supporting SD memory card expansion will restrict sales of versions in high capacity. Another reason is that the read and write speeds of SD memory cards are very slow. Even the fastest SD memory cards in the market only have one-tenth of those of today’s mobile phones. Comparing to some latest phones, the speed of storage cards is even slower than that. The user experience will suffer in such a circumstance. As a result, manufacturers of mobile phones have every right to control the weight issue. The solution is not to use SD memory card as expansion.
The speed of the mobile phone is not the reason for missing SD card slot. It is entirely a matter of price! When a domestic mobile phone increases to 128G, the price gets extra 300 yuan. While buying a 160MB/S 128G SD card, it costs only a few dozen yuan. It is clear that including a SD card slot, the net profit will get 200 yuan less. It all depends on the pricing, mobile phone suppliers will not care if customers desire high capacity or not. Invest less money with a phone with less memory. People expect additional phone storage when take pictures and videos. Also, WeChat images and videos take up a lot of memory. The 128G smartphone is insufficient! Therefore, internet users should avoid from the tricks and not purchase a mobile phone with a large capacity.
Mobile phone memory is expanding. Furthermore, chip updates and replacements are taking longer, and users save more content in mobile phones than ever before. When you switch phones, it takes hours for transferring more than 100 GB of content to the new phone. Then you need to spend hours on uploading and downloading data. That is just a phone of around 100 GB. How will you manage a smartphone that has larger storage than 500 GB and 1 TB in the future? The data in mobile phone is not 100% safe, you may accidently lose it or suffer damage. Therefore, it is necessary to get a backup on memory. In fact, memory cards work quite fine. You can complete this process in a minute when you replace the memory card.
I enjoy listening to songs, and I need to download music tracks. I never make a phone purchase if there is no memory card, as the space is not enough.
The availability of a memory card is practical. The data may be disappearing if the mobile device gets breaks. Some people say that you can store your data in online disk. However, there is a download speed limit of the network if you are not a member.
Type-c connector is gradually replacing old USB port. Also, the detachable battery has altered to an integrated battery. You may barely find headphone jack in new phones, and only the charging port is available. In this way, it is convenient for selling blue tooth headphones. Additionally, the universal charger is no longer available, while the power banks are getting popular. It is a revolution of phones, why we still need keep micro-SD slot for storage?
Using an SD card has two main advantages. 1. Typically, the data will not get damage if you store it in card, it is a great protection in case the phone develops a problem. Moreover, you won’t be hesitant to reinstall the operating system after simply taking out the card. Second, you can simply change the card if you swift to another machine. Otherwise, how can you transfer anything 120G from the old phone to the new phone?
The bulk Micro SD card is in perfect working order. People love storing all important pictures and videos in the phone’s memory. While all unimportant music videos, TV shows and movies are stored on the SD card. If there isn’t an SD card, your phone is insufficient. And you’ll have to get a new one. This is how producers of mobile phones might generate revenue.
I like to take pictures, therefore I consider whether a bulk Micro SD card is available for a mobile phone. The storage of a mobile phone itself may not have enough room for the thousands of images, memory cards are the best solution. I was wondering if the SD card of the mobile phone can be exit and load with one key.

Samsung has made full use of the opportunity to develop the SD card product line, and launched another two SD card series, namely PRO Plus and EVO Plus. And this passage mainly focus on and test the PRO Plus memory card with 256GB capacity.
The good news is that your camera user manual will tell you the memory card format and the minimum speed level you need to buy. You need to figure out the capacity and choose your price range. Finally, you must be sure to use one card reader compatible with your card. Otherwise, you may find that the transmission speed is much slower than you want.
When you buy a car, it is important to buy a driving recorder as well, so that just in case of traffic accident, you will have video evidence. Also, it is important to buy a memory card for it with good quality.
